linux系统安装mysqlclient的时候往往会报错，导致django项目无法启动，本文主要解决这个问题
解决方式1：直接找到mysqlclient的whl安装包
python3.8-x86-64位
通过如下仓库，下载mysqlclient的安装包 ：https://github.com/HMTeen/Linux-Python-mysqlclient
通过远程连接软件复制到服务器
安装：
pip install mysqlclient-2.2.1-cp38-cp38-linux_x86_64.whl
其他适配版本的whl安装包
参考这位大神的仓库：https://github.com/xizhicode/mysqlclient_builds
解决方法2：先安装相关依赖，再单独安装mysqlclient
rpm --import https://repo.mysql.com/RPM-GPG-KEY-mysql-2022
yum install mysql-devel
yum install python-devel
pip install mysqlclient
解决方式3：根据错误信息找到根源，一步一步解决
先占个坑，我遇到的问题是
sh
Collecting mysqlclient~=2.2.1 (from -r ./requirements.txt (line 23))
